I was about to write a post about compiling the newest openCV 2.3.1 in Ubuntu with pandaboard, but because of the proxy network problem in Ubuntu software update and the right solution to the proxy network settings, this post was postponed.

In the last post instsalling openCV in Ubuntu with pandaboard a networking proxy problem was raised. The problem is relevant to software updates and installations in Ubuntu, before and after openCV installation. There were two general suggestions made in the previous post – finding a new network environment, or, properly setting up the proxy parameters.

In the last post of installing openCV in Ubuntu with pandaboard, the failure of software update of openCV was discussed. But if there was no alternative to switch to other working networks, then the only way to install openCV in Ubuntu is as the way showed in this post.
- first, downloading the OpenCV-2.3.1a.tar.bz2 from openCV wiki, selecting ‘other announcements’ then going to ‘for mac and linux’, the page will be directed to sourceforge in this page: http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/.

At the first beginning of post, I would like to remind a tiny, but sometimes may huge, problem in installing openCV at ubuntu with pandaboard – the network proxy setting. This tiny issue could be the fatal problem when it was not aware of. I had tried hundreds of times to ‘apt-get update’ but nothing worked out. After I searched the problem of ‘failed to fetch…’, I was not well informed about how severe that problem was. Until I tied to change the Ubuntu Software Center’s networking settings, I noticed there was an tap used for networking proxy purposes.

Someone in the comments asked where to get so much information about openCV learning and developing, well, one of my primary source to get openCV related information – as well as most people’s issues they are facing recently is the openCV mailing list – a good way to receive archived threads and discussions from lots groups such as yahoo openCV groups and google openCV groups, and even stackoverflow q&a forum, or maybe the canonical openCV wiki is also a good source.

@丕子‘s comment reminded me to broaden the review area to cover multi-objects detection. Apologise for not making clear what is about to review in the second part, as a continue review of people counting using openCV, as in part 1 the review did not tell a clear content structure.
@zhijie thanks for your kind wishes.
In part 1 the review mentioned some difficulties to apply openCV for people counting, including camera positions, specific detection feature (faces) and overlapping objects.
